Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.
|Lysuskard | Lysuhóll|
|Feature Name||Feature Type||Elevation||Latitude||Longitude|
|Lysuhyrna||Vent||64° 51' 0" N||23° 11' 0" W|

The Global Volcanism Program is not aware of any Holocene eruptions from Helgrindur. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Helgrindur page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
There is no Deformation History data available for Helgrindur.
There is no Emissions History data available for Helgrindur.
|Lysuhöll, Iceland's smallest volcanic system, consists of a chain of small cinder cones and vents along a WNW-ESE line cutting diagonally across the Snæfellsnes Peninsula in the center of the photo. The cones and vents of the Lysuhöll volcanic system, seen here from the ENE, are located between the snow-covered Helgrindur mountains in the foreground and the glacier-covered Snæfellsjökull volcano in the background. The latest eruptions from Lysuhöll occurred during the Holocene.

|An aerial view looking east down the Snaefellsnes Peninsula shows the Bláfeldarhraun lava flow in the foreground, which originated from a pyroclastic cone in the highlands. The cone and flow are part of the Helgrindur (Lysuhóll) volcanic system, which consists of a chain of small alkali olivine basaltic cinder cones and vents along a WNW-ESE line cutting across the central Snaefellsnes Peninsula.

|The terminus of the Bláfeldarhraun lava flow is seen in the middle ground to the left of the farm houses. The flow originated from the pyroclastic cone on the left-center horizon and descended in the large lava cascade visible in the center of this view from the south. The flow is one of several Holocene lava flows of the Helgrindur (Lysuhóll) volcanic system on the Snaefellsnes Peninsula.

There are no samples for Helgrindur in the Smithsonian's NMNH Department of Mineral Sciences Rock and Ore collection.
|Catalogue of Icelandic Volcanoes (Link to Helgrindur)||The Catalogue of Icelandic Volcanoes is an interactive, web-based tool, containing information on volcanic systems that belong to the active volcanic zones of Iceland. It is a collaboration of the Icelandic Meteorological Office (the state volcano observatory), the Institute of Earth Sciences at the University of Iceland, and the Civil Protection Department of the National Commissioner of the Iceland Police, with contributions from a large number of specialists in Iceland and elsewhere. This official publication is intended to serve as an accurate and up-to-date source of information about active volcanoes in Iceland and their characteristics. The Catalogue forms a part of an integrated volcanic risk assessment project in Iceland GOSVÁ (commenced in 2012), as well as being part of the effort of FUTUREVOLC (2012-2016) on establishing an Icelandic volcano supersite.|
|DECADE Data||The DECADE portal, still in the developmental stage, serves as an example of the proposed interoperability between The Smithsonian Institution's Global Volcanism Program, the MAGA Database, and the EarthChem Geochemical Portal. The Deep Earth Carbon Degassing (DECADE) initiative seeks to use new and established technologies to determine accurate global fluxes of volcanic CO2 to the atmosphere, but installing CO2 monitoring networks on 20 of the world's 150 most actively degassing volcanoes. The group uses related laboratory-based studies (direct gas sampling and analysis, melt inclusions) to provide new data for direct degassing of deep earth carbon to the atmosphere.|

|WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.|
|Large Eruptions of Helgrindur||Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).|
|MIROVA||Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.|
|MODVOLC Thermal Alerts||Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.|
|EarthChem||EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS).|
